Security Framework for Internet of Things

Abstract

The Internet of Things (IoT)-based smart factories present an opportunity for the manufacturing industry to embrace the industrial revolution, also known as Industry 4.0. Technologies such as artificial intelligence (AI) and big data analytics are deployed to ensure real-time monitoring of manufacturing operations in this era. The main objective is to enhance the production process outcomes. However, Industry 4.0 faces security challenges due to communication taking place in environments. This thesis work introduces an authentication and key agreement method that aims to secure communication within a fog-based industry 4.0 environment. The proposed security solution enables authentication and key establishment among various smart industrial devices, fog servers, and cloud servers. Through security analysis and comparative study, it is evident that this method effectively mitigates attacks while offering security and functionality attributes compared to other existing schemes. newlineCritical infrastructures, such as electricity utilities, clean water facilities, nuclear plants, and manufacturing industries, are under the control and supervision of industrial control systems. These systems have undergone changes due to Industry 4.0, the fourth industrial revolution, which emphasizes connectivity and flexibility through technologies like the Internet of Things (IoT) and cloud computing. However, this increased connectivity poses risks, as Industry 4.0 communication can be vulnerable to attacks when data is transferred over the Internet. An access control and key establishment scheme called ACKS-IA to secure Industry 4.0 communication is presented to address this concern. This scheme enables the management of access and the establishment of keys between devices, including smart devices and their connected cloud servers. We have conducted a security analysis of ACKS-IA using the accepted Burrows-Abadi-Needham (BAN) logic framework.
